Abstract

The invention provides a light guide plate, a backlight module and a display device including the same, and relates to the technical field of displaying. By means of the light guide plate, the backlight module and the display device including the same, the problem that the light-emitting center line of an LED light and the light-receiving center line of the guide plate are not coincident accurately in an existing backlight module is solved. According to the light guide plate, the backlight module and the display device including the same, the light guide plate is used for guiding the light emitted by the LED light on an LED light bar, a groove is formed in a light-entering face on the side portion of the light guide plate, and when the LED light is arranged in the groove in a clamping mode, the light-emitting center line of the LED light and the light-receiving center line of the guide plate are coincident. The light guide plate, the backlight module and the display device including the same are mainly applied to the field of liquid crystal display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a backlight module and a display device using the same. Background technique [0002] The light guide plate is an important component in the side-lit backlight module, which is used to convert the line light source into a uniform surface light source. [0003] figure 1 It is a partial sectional view of an existing backlight module, which mainly includes: a reflective film 11 , a light guide plate 12 , a diffusion film 13 , a prism film 14 , a light bar 15 , and a back plate 16 . Wherein, the LED light bar 15 includes a printed circuit board (Printed Circuit Board, referred to as PCB) 151 and a plurality of LED lights (Light-Emitting Diode, light-emitting diode) 152 welded on the PCB 151, the light-emitting surface of the LED lights 152 and the light guide plate The light incident surface 121 on the side of the light guide plate 12 is opposite, so that the ...
